Great thread, this caught me out last year too!
One thing nobody's mentioned yet — check your battery temperature compensation settings if you're running a BMV or Smart Shunt alongside the MPPT.
After two years of running a basic 30A split charge relay in my Transit-based camper I finally bit the bullet last month and fitted a Victron Orion-Tr Smart 12/12-30A isolated DC-DC charger.

@PennineVanLifer One angle nobody's mentioned yet — if you're mostly on shore power, have you considered just replacing with AGM again but dropping to a smaller bank?
